Internal compiler error: segmentation violation signal raised

[mikescchen]

Hi,

I'm using mpiicx and mpiifx 2024.1 to build CESM 2.3 alpha17b.

It's a big package, and I get an error message on building the "FMS" component like:

#0 0x000000000232d4ea
#1 0x0000000002394d07
(......)
#16 0x00001466ee72ad85 __libc_start_main + 229
#17 0x00000000020ab129

/tmp/ifx0411443332gzWO2u/ifxUZkYJp.i90: error #5633: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error.
compilation aborted for /home/u8935479/cesm2_3_alpha17b/libraries/FMS/src/fms2_io/netcdf_io.F90 (code 3)
gmake: *** [/home/u8935479/cesm2_3_alpha17b/libraries/FMS/Makefile.cesm:362: netcdf_io.o] Error 3

The system's a supercomputer with RHEL 8.7.

We're going to fallback to mpiifort 2019.5 for now, but would be happy to provide more information to get this solved in the future.

Thank you for reporting this. It looks like the internal compiler error (ICE) occurred while compiling netcdf_io.F90.

Can you please post that file and any other files required to successfully compile netcdf_io.F90? A tarball or zip file would be great.

What compiler options are you using?

Hi,

Thanks for the reply!

As stated, this is part of a much larger package (CESM from UCAR: https://www.cesm.ucar.edu/), I'm not sure if you can reproduce the error without going through the workflow.

Anyway, I've attached the source code and the error log message in the file.

Also, is there some kind of flags that can make mpiifx give more information on the error? I think I can modify the makefile so we don't need to copy the whole thing elsewhere.

Please let me know if you have further suggestions.

Thank you, @mikescchen. I just learned that that issue has already been reported. The fix will be available with the 2024.2 release that is planned for mid-2024.

A workaround is to compile netcdf_io.F90 with -O0 and there is no error.

[mikescchen]

OK Thanks!

I'll see if I can get this -O0 set in the workflow.

Mike
